I did look around and came up with this chart: http://www.babyhopes.com/pregnancy-t...nsitivity.html
Uh...but I found a whole bunch of other sites claiming differnt mIU levels than those shown here. LOL, I suggest trying the store brand of whatever is the closest to you - that seems easy. A lot of the #s seems really far off from other charts, so I don't know how much I'd trust it but at least there are some numbers!
